SOLE-PBESSING MACHINE Application filed May 28, 1910. 1 Serial No. 563,838. I

To all whom it may concern Be it known that I, BENJAM1N F. MAYO, I

a citizen of the United States, residing at Salem, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Pressing Machines; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled. in the art to which it appertains to make and use the same.

The present invention relates to sole pressing machines which are employed to lay and level the soles of boots and shoes Heretofore, these operations have generally been pertormed by machines of two classes or types, commonly called direct pressure and rolling pressure machines, respectively. In the former class of machines a sole pressing mold or form is employed which is applied under pressure, to the entire surface of the sole simultaneously by a relative movement of shoe supporting jack and sole pressing form directly towardeach other in a straight line, the form being suitably shaped to press or mold all portions of the sole at the same time into the desired shape or contour. lVhile this type of machine tends to mold the sole invariably into the same shape or contour, on account of the simultaneous engagement of its form with all portions'of the sole, difliculty is often experienced in properly laying or lev-' eling ce tain portions of the sole, particularly the shew 1: portion, on account of" the comparativcr light pressure per unit area under which the machine is obliged to operate, for otherwise the wooden lasts which are commonly employed to support the shoes when they are subjected to the action of this machine would be broken or damaged by the heavy total pressure exerted upon the sole as a whole by the simultaneone application of pressure to all of its parts. In the rolling pressure machines, on the other hand, a solo pressing form or roll is employed which is applied temporarily first to one portion of the soleand then to another by a relative oscillating or rolling movement of form or roll and jack. These machines, however, although capable of operation under a much higher pressure-per unit area than direct pressure machines without endangering the-lasts, apply their pressure along what practically only i Specification of letters Patent. Patefitedtf I line contactbe'tween the form or rollaridlq sole and extending across orfonly partially across the latter.; As a-consequence, ma-

chines of this type tend to produce soles. of

different and v'aryingshapes and contours.

Moreover, the progressive relative movement of the form or roll along the sole while in contact therewith distort the sole One of the objects-0f 'thepresent inven} tends to displace and tion isto devise a sole pressing machine employing a sole pressing form which (shall I,

subject the shoe sole, to a. sufficiently heavy;

pressure per unit area. to mold tlie'sole to the exact shape 'orcontour deslred, yet with{ out causing so heavya total pressure a) be imparted to the lastthat it is'l liable to be broken or otherwise damaged. This result is obtained by mechanism so constructed and operating that a heavy pressure will heapplied success vely to substantial portions 'of' the surface of the sole,such pressure being subsequently relieved in whole or onlyin part so that at no time is the total pressure upon the lastsufiiciently hightofracture or to otherwise damage it".

Another ob]ection not only to direct pressure machines but also to those-rollingpres:

sure machines employing a form'is that 'no' to apply pressure to one portion of the shoe sole, such as the shank portion, either heavier perunit area or fora greater nun] ber of times or for a longer duration of time. than to other portions such 'as the ball and toe. butin order that these prior ma-i chines may properly lay or level-the most clitlicult portion" of the sole all the remaining portions must'loe subjected to a heavier" pressure or to a' greater number-of pres the present-- inven{ n'ei'erahly to thesha-nk. a heavier pressure.

is in inoperative position to permit the introduction or removalof the work or the making of necessary adjustments.

In t ese drawings, Figure 1 is a side, and Fig. 2 a front, elevation of such a machine; Figs. 3 and 4 are vertical sectional views of 1 the shoe supporting jack and of the sole pressing form, the latter being shown in Fig. 3 in inoperative position and out of contact with the shoe sole, and in Fig. 4 in inoperative position and in contact with the sole; Fig. 5 is an enlarged vertical section of the sole pressing form and the carrier 6 is a front elevation of a ortion of the form and carrier; and Fig. 7 1s a transverse sectional view of the same on line'.7-7, Fig. 5; Fig. 8 is a top plan view on line 8-8, Fig. 1, partially in section, of the shoe supporting jack and its adjusting mechanism; and Fig.- 9. is a transverse sectional view of the same on line 99, Fig. 4.

Since the two sets of jack and form mechanis'ms, as well as their actuating devices, are'identical, only a single set. will be described in detail.

In the. specific form of the invention, which is illustrated in the drawings, the 3 hoe is supported upon a jack normally held in fixed position and a flexible sole pressing form comprising a plurality of sections hinged or pivoted to one another is applied to the sole, one portion or sect1on at a time,-by a spring-pressed roll or carrier over which the form is wrapped or wound, the rolling of the carrier alongthe shoe unwrapping the form and laying it upon the shoe sole. The carrier when rolled in the reverse direction wraps or -winds up the form, carrying it out of engagement with the sole of the shoe. A plurality of springpressed rolls are provided which follow directly behind the carrier in its form-applying movement, which rolls engage the back or upper surfaces of the sections of the form and apply 'andmaintain pressure on the form.

As shown in Figs. 1, 3 and 1, the last 1 which carries the shoe, the sole of I to be laid or leveled, is supported in the usual manner at the heel and toe' -zloy the heel and toe supports 2 and 3, resp '('ti'vely, of, the jack carried on the frame Cot-the mag other deisms as 'iivill be apparent power and/constructed which is chinet- Pivoted upon the horizontal shaft 5,

which is fixedly secured in suitable supports or bearings at the front of the machine, are

the sectorjlevers 6, projecting from the hubs 7 of which are the actuating arms 8. The

ctorlejvers 6 are provided at their extiemities? with the arc-shaped Portions 9 in .which are formed a plurality of parallel sided radial'slots 10, the front end of the arc-shaped portions being formed with a projection 11 having the parallel-sided, radial .slot 12. Mounted in the slot 12 in each sector lever 6 is the bearing block 14 in which the shaft 15 is rotatably mounted; Rigidly mounted upon this shaft is the form carrier which comprises the hub 16 and a semi-cylindrical body portion 17, in-

tegrally connected with the hub by means of the radial arms 18. The outer face of the semi-cylindrical portion 17 is formed with a plurality of slightly concaved, arc-shaped faces, the axis of the shaft 15. v

The sole pressing form shown in enlarged detail in Figs. 5, 6 and 7 is a flexible form and comprises a plurality of sections or links 21 pivoted to one another and each carrying a sole engaging'piece 22 composed of some,suitable slightly yielding material such as rubber, and having its outer surface of the proper and desired contour for that portion of the shoe sole with which it is to be brought into contact. The method of connecting the sections orlugs 21 is perhaps best illustrated in Fig. 6, where each link is shown as being provided with two lugs or projections 23 on what would be the rear edge of the .link when the form is in contact with the shoe sole, which lugs come just within the lugs 24 on the front edge of the adjacent link, a pivot pin 25 passing through the two lugs 23 and 24 and securing the sections or links together. Each link or section is also provided with a recess 26 in its rear edge and a correspondingly shaped projection 27 at its front edge, the projections on one link entering the recesses in the adjacent link, thus breaking the ing members 22 to the links 21 comprise screws 28 passing through the projections or bosses 29 on the links and entering the members 22.

a While the sole pressing form, as illustrated in the drawings and as above described, constitutes a combined flexible and sectional form, the present invention. except the elements of which are parallel to Where so specifically defined, is not limited.

to such a construction as it is evident that, with either a flexible or a sectional form not:- only may pressure be applied progressively and successively to one portion of the sole after another, but different pressures both as to amount and as to duration may be imparted to different portions of the sole.

The heel end of the'form is anchored to the post 31 whichis mounted in the block 32 secured upon the jack support, the post being arranged for a vertically yielding movement against the coiled spring 33. The

toe end of the form is pivotally connected to the lugs or bosses 34 on the carrier. Except for these attachments of the rear end of the rear section to the post 31 and the front "end of the front section to the lug 34, the

1mm is free and unsecured, the intermediate port-ions being supported upon the faces 19 of the carrier when in inoperative position, as shown in Figs. 3 and 5, or resting in engagement with the shoe sole, as shown 1n Fig. 4, when in operative position.

It is obvious that if the sector lever be actuated by suitable mechanism to move it to the left as shown in Fig. 3, the form cargr ier will be. oscillated anti-clockwiseby the as -form itself, the rear end of which is anchored as described, and the form will be laid, one portion after another, upon the bottom of the shoe sole. until the parts have been brought into the position shown in Fig. 4. In order that a reverse movement of the sector lever shall cause the carrier to oscillate in the opposite direction and to wrap or wind up on itself,'as it were, first one portion and then another of the form, mechanism has been provided which operates independently of the form to accomplish this result. This mechanism comprises a grooved wheel or pulley 37, rigidly secured to the shaft 15 upon which the carrier is fixedly 40' mounted, a fixed segment 38 mounted upon the frame of the machine and having a groove in its peripheral face, and a wire 39, or other flexible connection, one end of which is secured at 41 in the front end of 45 the groove of the fixed segment while the other'end is secured at 42 in the grooved wheel 37. The lead of the wire is best shown in Fig. 3, extending in the groove in the fixed segment from its'point of attachment at 41 nearly to the rear end of such segment and thence passing around the back of the pulley 37 and in its groove to the point'of attachment at 42. Vhen the sector lever is moved to the left, as shown in Fig. 3, the oscillation of the form carrier causes the wire to be wound around the grooved pulley 37 the wire finally assuming the position shown in Fig. 1 on the left-hand grooved pulley. On the reverse or rearward movement of the sector lever, the wire being anchored at 41 acts jpstms did the form in the forward movement and compels the carrier to oscillate in a clockwise direction and to wind upupon itself the formz It will be noted that the above described mechanism positively oscillates the carrier in its form removing movement and insures the proper positioning of the form upon the carrier and its subsequent application to the sole oflthe next shoe.

The pressure applying devices which act to force the-form strongly against the shoe sole toflayo' level the same, include not only the for arri'er itself which preferably exerts a, vy pressure upon each portion of the'fo n as it is brought into contact with a-portion of the shoe sole, but also a series of supplementary pressure applying devices in the shape of spring-pressed rolls carried by thesector lever and caused to roll over a greater or less number of sections of the form after it has been brought into contact with the shoe sole. The form carrier acts as a pressure applying device through the medium of the relatively heavy coiled springs 45 located in the top portion of the radial slots12 in which are mounted the bearing blocks 14, which in turn support the shaft 15 carrying the form carrier. The lower end of the springs 45 engages the top of the bearing blocks 14 while the upper end of each spring bears against a washer or pressure plate 46 adapted to be adjusted up and down in the slot by means of the adjusting screw 47 to adjust the pressure exerted upon each section of" the form as it is brought on to the shoe sole.

The'supplementary pressure rolls 51, of which four are shown in the machine illustrated in the drawings, are rotatably mounted in bearing blocks 52 located one in each of the radial slots 10 in the sector levers 6, the blocks being normally pressed inward toward the axis of the levers by the relatively light coiled springs 53, one end of which engages directly with the bearing block while the other bears against a washer or pressure plate 54 arranged to be adjusted through the medium of the adjusting screws 55 to vary the pressure exerted by the rolls 51. If desired, these springs 53 ma be put under different degrees of compression according to the portion of the sole to which they apply pressure. For example, the supplementary roll next but one to the form carrier may be under a heavier spring pressure than are the adjacent rolls on either side so that when the parts are in the position illustrated in Fig. 4, a heavier pressure will be applied to the shank than to either toe or heel.

As shown in Fig. 4, the shape of the yielding engaging pieces 22 and the sections 21 of the form are such that when the form is in operative position upon the shoe, what is then the upper surface of the sections constitutes a substantially continuous, curved surface closely approximating the form of an arc, the center of curvature'of which is the axis of the sector levers 6, so that the supplementary pressure rolls 51 will roll over this surface, each roll in turn applying pressure to. each: portion over which it passes. It is obvious, however, that a greater or less pressure can be applied not only by the form .carrier but by the supplementary rolls as Well, to any particular or desired portion of the form by increasing or diminishing the thickness of the section overlying the portion of'the sole in question. Preferably the sections over the shank portions of the sole 'will be slightly thicker than those over other parts, in order to increase the pressure upon the shank.

As already pointed out, the pressure spring 46 oi'the form carrier is a relatively section of the form which operates upon a substantial portion of the surface of the sole to be applied to that portion under a'pressure per. unit of area, which, if necessary, may. be so heavy that if applied simultaneously to the. entire surface of the shoe sole would be liable to break or seriously damage the wooden last upon which the shoe was supported. WVhile the spring pressure of the supplementary rolls may be very substantially less than that of the form carrier, still they are sufiicient to exert a very material pressure upon the form, which will also as sist in the laying and leveling operation. As shown, the sections of the form are of such a length in the direction of the longitudinal axis of the shoe, and the supplementary rolls are of such a number and spaced such a distance apart that not only will the various sections of the form, after they have been applied. to the sole by the form carrier,

be maintained underat least a substantial minimum pressure, but the pressure will vary being increased from, and then reduced to, this minimum from time to time, as the form carrier and rolls passover the sections of the form. At no time, however, will the total pressure exerted through the form upon the wooden last be suflicient to fracture or injure the same.

In the specific embodiment of the invention illustrated in the drawings, the form is applied first to the heel and then progressively along the sole to the toe, and when the form. is removed the reverse'operation number per ncl takes Ii -p late, first the toe portion, then the ball, and. finally the shank and heel portions being'removed. Such an arrangement and operation, it will'be observed, enables pressure' to be applied to the shank portion,

which ordinarily is the part of the shoe sole most difiic'ult to lay andlevel, for a longer period of time than tothebalhand toe portions, since it is applied to the sha k portion of the sole soonerand removed 1 rom it later than at the ball and toe p Moreover, the shank portion is sub e ted to a greater number of pressures than lie the ball and toe portions, since the sharEk sections of the form are acted upon byte sec& ond supplementary roll in the series, swell as by the form carrier and the first r ll, the

"ball and toe portions at the most ,1, aving pressure applied through the form 'carrier and only the first of the supplemental rolls, If desired, however, pressure ma be applied progressively over. the sole rom. any

mounted upon the horizontal. guideway' 58 (see Figs. 8 and 9) of the jack, being adjusted by hand along the same and secured in its adjusted position by the set screws 59 The heel and toe supports 2 and 3 are also adjust-ably mounted upon the guideway- 58 to permit their being moved nearer to or farther from each other according to the size or length of the shoe they ai'e to support,-

and this adjustment is effected by' meansjof the threaded shaft or spindle 6-1 mounted in a bearing in the upturned end 62 of the guideway and held from longitudinal 'movement by the collar 63 on the back side of the bearing and the hub of the adjusting hand wheel (ii on the front side. The front and the rear portions of this shaft are oppositely threaded, one portion being provided with a right-hand thread, and the other with a left hand thread, .each portion passing through correspohdingly threaded holes in the depending bosses or lugs 05 and 66 on the bot-Y toms of the heel and toe supports respectively. A rotation o'f the adjusting hand wheel 64 in one direction moves the heel and toe supports toward each other, while if the hand wheel'be turned in the opposite direction, the supports, will be moved apart. It is desired, however, to position the shoe by the heel support than the! toe support, the th'reads upon the spindlev are given a difl'ment pitch orgnumber per inch, those on --the rear portion beingofless pitch or of greater than on their-out portion. nd' wheel 6* is rotated a less rate than toe support is moved along theguideway toward or from the heel.

As shown in Fig. 9, the bottom piece 71 which, as shown in Fig. 3, is fixedly secured to the frame of the machine by the screws 72, is provided with the guideway '73 in which is mounted to slide the adjusting piece Tl hating the inclined slots 75 in its front and rear portions. A threaded adjusting spindle 76 mounted in bearings in the front wall T7 of the bottom piece 71 is provided with a squared nut 78 to receive a wrench or handle whereby the spindle be turned to adjust the piece Te: forward or backward in itsguidcway in the bottom piece 71. cured to each side of the piece 71 by the screws 81 are the sidepieces 82 having the vertical slots 83 (see Figs. 4: and 9). These slots receive in their upper portions the provision being made, howeverffor stop ings, it of advantage 'tog so construct and arrange the controlling mechanismthat, normally, when one set of mechanisms is set into operation, the other set w1ll cease operation,

In United States Letters Patent No;

' 861,746, granted July 30, 190.7 ,is shown acstuds Sat which are screwed into the V-shaped bosses 85 extending downward from each side of the guide piece 58. In the lower portion of the vertical slots 83 are the ends or heads 86 of the studs 87. Secured in the bottoms of these ll-shaped project-ions 85 are the middle portion of these studs which pass through the inclined slots '75 in the adjusting piece 74. If it be desired to raise the toe and heel supports, it is only necessary by means of a wrench or other suitable device to rotate the adjusting spindle 76 in such a direction as to force the adjusting piece 7% reamvai'dlv which will cause the inclinedslots to force the studs 87 upwardly in the vertical slots thus raising the guide piece 58 and all the parts, including the toe and heel supports carried thereby. Rotation of the spindle in the opposite direction lowers these parts.

The actuating mechanism for each sector lever consists of a crank upon a shaftconnected with the arm 8 of the sector lever, a power-shaft, suitable speed reducing devices between the power and the crank shaft; and mechanism for controlling the rotation of the power shaft. in order that the sole may be properly laid or leveled, it is desirable that the actuating mechanism for the form be so designed that it may repeat its cvcle of operation one or more times at the will of the operator, and preferably that after such mechanism has been once set in operation. it will continue to operate until thrown out of operation by the attendant. It is also desirable on this classof machines that the mechanism should automatically come to rest in the most convenient positirjm for the operator to remove the old work and insert tuating and controlling mechanism.-which I had invented and embodied ina sole press- 7 5 ing machine of the rolling pressure type. Inasmuch as substantially the same mechanism is employed in the sole pressing machine which forms the subject of the present invention, any detailed description of the same is unnecessary, the construction and mode of operation of such mechanism being fully set forth in the above-mentioned patent. Briefly described, the actuating mechanism for the sector levers consists of two crank shafts 91,; disconnected from one an-v other but with coincident axes. Each crank 92 is connected by means of the, link 93. with the .end of the actuating arm 8 of the sector lever 6. Secured upon the end of. each shaft and outside the frame ofthe machine is the large gear 94: which engage'sthe worm 95 upon the power shaft 96. Loosely mounted upon the rear end. of the shaft is the driving pulley 97 which forms one member of a 95 cone clutch, the other member being rigidly secured upon the shaft. A movement of the driving pulley to the right in Fig. ,1

causes the clutch members to engage, and

starts the worm and gear inoperation, wh'il v.1100

' a movement in the .oppositedirection disconnects the clutch andstops the form carrier actuating mechanism." Two treadles lQl',

are provided, conveniently located for. the operator at the front of the machine, wh m-105 through a trainof mechanism-which need i not here be described, actuates the shipping lever 10:2 to causethe clutch to release or engage and the brake shoe 103 to be thrown into or out of Contact with thebrake disk 11o,

10lon the power shaft. The earn .105 on the end of the crank shaft operates, as fully I set forth in the patent referred to, through the lever 106, to cause the actuating mechanism to be automatically thrown out of op- 1 1 5 eration only when the sector lever has reached its backward position, as shown in. full outline in Fig. 1. The driving. belt is led from an overhead countersha ft around and beneath the loose pulleys 97, passing 1-20- hape having been secured upon the form-carrier, fithelast with the shoe upon it is placed in pos1t10n upon the ack and the machine set in operation by pressing down the proper treaclle. As the sector lever swings forwardly, the form is applied one portion at a time to the sole of the shoe, beginning at '-the heel, and under the heavy pressure of the form-carrier springs, and as the carrier advances over the sole one after another of the supplementary pressure rolls are brought into contact with the upper surface of the form and impart a rolling pressure to the sole. After the crank passes its center ithe'sector lever moves rearwardly, carrying the .;sfupplementary rolls along theform and finally out of contact therewith, while the form-carrier removes the form one portion at a time from the sole. In the meantime the operator is adjusting another last with its shoe upon the other jackv of the machine and as soon as this is accomplished depresses the other treadle to start the other set of .mechanism 'in operation, at the same time bringing the first set to rest so that the shoe and last may be removed and another shoe on its last inserted in the machine. I If. it be'desired to stop one set of mechanism 'without starting the other n operation this may be accomplished by partially depressing the starting treadle as set forth in said United States patent No. 861,7 t6,

In the preceding specification and in the accompanyingdrawings What is novv considered the preferred formof the present 1n-. 'vention has been described and illustrated.-

It is tobe understood, however, that the present invention may be embodied'in many other anddifferent forms of mechanism 40,

without departing from the spirit thereof.
